Depending on your application's needs, your choice of boilerplate may differ.
The one thing to keep in mind is what the production application structure should look like when deploying the application.

We provide a boilerplate of our own that is meant to facilitate development, but does not assume anything other than your application's source code entry points (index.html and index.js). It is not as mature as the above, but for your consideration, this is why we use it:

simple to understand and extend

minimal infrastructure only - no non-vanilla technology is assumed
